Odd TV news clip of the week: woman can MSNB-See (but not hear)

I haven't watched MSNBC since my cable company took it off the basic digital package I have, and between the bizarre Keith Olbermann/Chris Matthews feuds and stuff like the video below, I might have to upgrade. It's from yesterday, when David Shuster and Tamron Hall were interviewed by a New York reporter about a story she wrote. It gets very odd. If she couldn't hear them, how did she answer so quickly? And if she was reading the screen and answering some questions, why not answer the others?
